A basic function of a node is to receive packets and examine the packet's field (header) by identifying its destination address and source address. This task is performed by classifier that sit in the node.

There are several types of classifiers for different purposes. A classifier provides a way to match a packet against some logical criteria and retrieve reference to another simulation object based on match results. Each packet received will be matched with the slot numbers indexed in the classifier.
